Yep, nothing wrong with it. I don't think she would come to any serious harm if she were to loose balance... Unless of course the photographers were the types to watch on as she choked to death. Which is probably unlikely.

Now, if she was standing on a wood block 6' high and barely thicker than her shoes and say about 5' of slack in the rope between the noose and a sturdy tree branch I would have to say that the photographer either falls into the "psychotic" class or is good enough at Photoshop to fake it.
